This may sound like a silly request, but I'd like more font and formatting options for reading in the Kobo app. I downloaded a preview of a book using the Kindle app on my Arc, but purchased the book via Kobo. Imagine my surprise when I discovered the formatting and font choices available in the Kindle app were much better than what's available in the Kobo app. It would be great if we were able to change margins, and to use fonts other than Droid Serif/Droid Sans Serif in the Kobo app.
